Y 2 Claims. (Cl. 146-146) This invention relates to a functionally and structurally improved cutting machine capable of use'in numerous different associations and Vof particularv'alue when employed in connection with the vending `of commodities such as cheese and other products of similar consistency. i 1 Y It is an object of theinvention to furnish anV apparatus of this nature in which the thickness of the slice to be dispensed or vended .may vbe varied according to the'desires of the person using the machine, such variation being achieved `with practically no effort on the part of the operator. l

A furtherobject of the invention is that of conl5 structing Aa slicing machine in whichV the parts will not clog and in which each slice will ber of uniform thickness.`

Another object is thatof providing an apparatus of this character embodying relatively few parts eachindividually simple and rugged in construction and capable of ready assemblage to furnish a cutting machine operating overV long periods of time'with freedom from mechanical difliculties even when employed by unskilled operators. Y n

With these and further` objects in mind, reerenceis had to the attached sheets of drawings, illustrating practical embodiments of the invention, and in which: i

and knife carried thereby may be swung down- Fig. l1 is a sectional side ViewV of the unit as shown in Fig. 10. x

In these views, the numeral l5l indicates the supports for a deck or platform 16 which as shown is preferably inclined to the horizontal 60. and may have longitudinally extending corrugations or grooves 17 which serve adequately to support the article to be'sliced and to retain the `same against accidental displacement. This article, according to its size, extends overa greater` or lesserportion ofthe base or deck, but in any event, bears against the lower end of the same at which point it also rests against the end wall 18 which is preferably extended at right angles `to the plane of the deck.

Mounted upon. a shaft 19-extending below the deck is a knife support 2O which may have a U or hook shapedv inner end and preferably supports Aat its outer end` a handle 21 by rneansof which `it may conveniently l be manipulated 75 I Moreover, Vthis support preferably carries a guard .22 extending beyond the cutting edge of a `blade 23, -it being obvious that by this expedient together with constructions hereinafter described the ngers of the operator will be protectedvto a maximum extent. Moreoven'due toV the hook shaped inner end 20 ofthe knife -holder or-carrying member, it will'be `obvious that as the blade swings downwardly in proximity to the delivery edge of the deck that awiping stroke will 55 result"` instead of a vstraight crushing action. Movement ofthe holder and knife beyond pre-V determined points may be prevented in any de-Y sired manner by for example extending the holder 20 as has been indicated'at 24 and to provide in 90 cooperation with a pin 25 extendingfrom below the deckoi` the machine a construction acting as a stop. Y f

Ina machine of this character, Vit is usually necessary to provide a construction acting to limitmthe distance to which the article to be sliced may be projected, and thus accordingly to limit and control the thicknesses of the slices into which the article is' cutj. -With this in mind, the present machine includes 'a stop or gauge plater26 which isY mounted upon a shaft 27, this Vshaft `being coupled tothe shaft 19 by forexwardly from the position shown inthe first iigure and the stop plate Will not have a movement as great as that of the knife and holder. Accordingly, .an article resting upon the deck and 5 bearing against ther stop plate will remain even under constant pressure towards the stop plate in proper position until the `edge of the yknife engages itandin fact the support and'restraining influence exerted by the stop plate will not cease until the cutting edge has cut substantially throughr the entire body of the article being sliced. To again prevent accidental displacement.

of the article although preventing any binding tendency of the parts, the Aface of the stop plate may be grooved arcuately as has been vindicated at 31, these arcs being segments of concentric circles having as their center the shaft 27.

Now with a view to providing a suitable mechav nism whereby the distance between the edge of 36 forming a part of this'knob in contacty withv the projection 33. This cam edgeas shown preferably presents rest portions' corresponding in number and in depth thereof to the graduations presented by the knob. In view' of the fact that the spring normally serves to impel the shaft 27 outwardly, a turning of the knob will serve to space the stop 26 to a greater or lesser extent from the plane of the outer or delivery edge of the deck. Accordingly, with each elevation of the holder and knife and under continued pressure uponthe article being sliced, this article will move to a point where it contacts with the stop plate and according to the position of the latteras controlled by the knob 32-the slices will be of any desiredv thickness. 'Y Y In certain instances, it may be desired to prevent anyy possibility of adhesion between the slice and stop plate. With this in mind, the stop plate may be given a movement away from contact with the outer'face of the article being sliced as the latter is severed. 'VA convenient construction according tothe present inventionto accomplish this result is disclosed in Fig. 5in which the shaft 27 is hollow as has been indicated at 37,

and there ridges within this shaft or tube a second shaft 38 to the outer end of which there is rotatably attached the knob (not shown). Connection between the tube 37 and the shaft 38 is afforded by a pin and slot construction 39,:the slot being inclined inf'the direction of the delivery edge of the deck. A guide structure 40prevents rotation of the shaft 38. YAccordingly as the knob 32 is turned, this shaft is adjusted 1ongitudinally in the manner afore described Yto vary the thickness of the slice, this being accomplished due to the fact that any thrust up'on the' shaft will be transmitted by the pin and slot connection. However, as afore brought out, lthestop or gauge plate swings and this is accomplishedby rotating the tube 37. Accordingly, withthe parts properly set,.proper thickness of slice is initiated and the cutting edge of the blade bears against the article to sever a desired portion of the same. As this movement of the parts occurs, the tube 37 rotates with respect to the shaft 38 thereby causingthe pin to traverse the slot causing the tube to f to give increased' slicing thickness.

`ticularly through the final severing stages of the slice; Consequently, the stop plate separates from contact with the outer face of the slice and free delivery of the latter is effected.

vIn certain instances, it may not be desired to employ this construction. Within certain limitations, the same results may be achieved by the usel of a stop plate 4l having a rearwardly inclined face 42. Under normal operation of the parts, the article'bears against the inner face of the plate. A downward swinging of the holder and knife causes contact to be effected between the cutting edge of the latter and the article and thereupon under continued downward swinging of the plate the face of the latter-due to its tapered construction--clears the slice being cut.

In the form of construction shown in Figs. 8 and 9, adjustment of the shaft 43 which carries the stop plate .may be achieved by the use of a lever 44 having its inner end pivoted and its outer end carrying the knob 45 registering with graduations 46 arranged for example in the face of an extension forming a part of the machine. Obviously, as the level is shifted, the shaft will be shifted to vary the thicknesses of the slices. The additional advantage arises by this construction that if the zero or minimum slicing .thickness occurs with the lever set at substantially right angles to the shaft 43, this Vlever will have its slot 47-within which the pin 48 of the shaft 43 rides-extend angularly as the parts are adjusted Consequently, the shaft 43 in rotating will move slightlyout- Wardly again giving the advantage of clearance between the end slice of the article and the inner face of the stop plate. t

Where such movement is not' desired, thev results may be achieved by substituting for the pin and slot connection 47-48', a pin 49 carried by the lever 44 and riding within a groove 50 formed in the'shaft 43. Obviously, under this construction, the desired adjustment will be accomplished without, however, there being any outward movement of the shaft except when adjustment is made to vary the thickness of the slice.

In each instance, it will be appreciated that the knife serves as a stop for the main body of the article and duringthe slicing of the latter.

/ After severance of the slice, the article does not move forward until the knifeclears the same whereupon under continued pressure the article shifts and contacts with the stop plate. If desired, the paper holder or shelf 5l may be associated with any convenient portion of the machine and the latter may have a recess accommodating an oil stone or sharpening element 52 which is retained by a spring clip 53. Also,

it is preferred, according to the present invention, and as has been indicated in Fig. 4, that the cutting edge of the knife 22 may be formed by an outwardly extending face 54 which lies at an acute angle to the inner face of the -blade and which face is continued in a-secondary face 55 extending at an obtuse angle to the first face. By this construction, adhesion between the article being sliced and the face of the knife is prevented. Obviously, any number of changes in construction may be resortedto without departing from the spirit of the invention as defined by the claims. v Having described my invention, what I claim 2. A slicing machine including, a deck, a knife pivotally secured to one end thereof, a Vstop plate pivotally mounted by said deck adjacent said knife and adapted to move in -a plane substantially that of the path of movement of said knife, said stop plate being formed with a sloping inner surface; means coupling said knife and stop plate for simultaneous movement about their pivots,v

and further means for causing an automatic lateral movement of said stop plate away from said deck as saidrknife is lowered.
